The Shimano SLX M671-A 10 Speed Top Pull Front Derailleur gives you a clean cable routing to decrease problems with tyre clearance. There is also an increased suspension stroke thanks to the new slant shaped left linkage design. You can either buy it in Direct Mount or Multi Fit on the conventional swing derailleur. This is Top Pull only, which increases the tyre clearance on 29ers, & is Dyna-Sys 10-speed MTB drivetrain compatibility.
